About Sophos PureMessage for Exchange

Sophos PureMessage for Exchange is a Microsoft Exchange anti-virus tool comprised of three components: Microsoft Exchange anti-virus protection, application-level anti-spam protection for Microsoft Exchange, and the Sophos On-Access File Level anti-virus scanning. This plug-in does not protect the Sophos On-Access File Level component.

Sophos PureMessage stores all quarantined files in a database. If the Quarantine database is stored locally on the server, but the SQL instance used is not named "SOPHOS", then it can be protected using the Neverfail for SQL Server Plug-in. The "SOPHOS" instance is protected by the Sohpos plug-in.

The following versions of Sophos PureMessage for Exchange are supported in respect to the hardware platform:

x86 Platform (32-bit hardware)

  • V2.5 on Microsoft Exchange 2003
  • V2.6 on Microsoft Exchange 2003
  • V3.0 on Microsoft Exchange 2003

x64 Platform (64-bit hardware)

Protected Services

This is a list of all services protected by this plug-in. Please note that where a plug-in supports multiple vendor versions, some services may not be present in a particular version.

The Sophos PureMessage services are monitored and controlled by the plug-in. When the plug-in is installed, all protected services will be set to 'Manual' unless otherwise stated.

The following services compose the Sophos PureMessage for Exchange anti-virus:

  • Sophos PureMessage Running Object Table (ROT) (MMRot) - Manual
  • Sophos PureMessage (Savexsrvc) - Manual
  • Sophos PureMessage (SavexWebAgent) - Manual
  • Sophos PureMessage Scanner (PMScanner) - Manual

The other services, used by the File Level Scanning Components, also are present on the server:

  • Sophos Autoupdate Service - Manual
  • Sophos Administrative Service (SAVAdminService) - Manual
  • Sophos Anti-virus Service (SAVService) - Manual

The Autoupdate Service is also monitored and started via the plug-in. It is left on the default start-up, which is 'Manual'.

As the plug-in protects the default Sophos instance, the following services are also protected ONLY if the SQL instance "SOPHOS" exists:

  • Distributed Transactions Coordinator (MSDTC)
  • SQL Server Browser (SQLBrowser)
  • Task Scheduler (Schedule)

Protected Data

This is a description of the protected data set that was determined when the plug-in was installed. Please note that exact filters will be based on the configuration of the application plug-in during installation.

File filters data:

  • Protects the Sophos PureMessage for Exchange configuration data and logs.

Registry filter:

  • This plug-in protects all the registry information stored for the Sophos anti-virus product suite.

Automatic Filter Discovery

This plug-in does not provide a filter discovery component. The plug-in will need to be reinstalled using the procedures to uninstall and reinstall a plug-in included in Knowledgebase article #1512 - 'Plug-in for Sophos PureMessage for Exchange - Online Help' if the application is reconfigured so that new locations are specified for files that are currently protected.

Unsupported Components or Features

The plug-in does not protect the following application features or components:

  • Does not control the Sophos File Level anti-virus services.
  • Does not protect the Sophos File Level anti-virus configuration files because these are in use on the passive server.
